Carrier-phase synchronization can be approached in a general manner by estimating the multiplicative distortion (MD) to which a baseband received signal in an RF or coherent optical transmission system is subjected. This paper presents a unified modeling and estimation of the MD in finite-alphabet digital communication systems. A simple form of MD is the camer phase exp GO) which has to be estimated and compensated for in a coherent receiver. A more general case with fading must, however, allow for amplitude as well as phase variations of the MD. We assume a state-variable model for the MD and generally obtain a nonlinear estimation problem with additional randomly-varying system parameters such as received signal power, frequency offset, and Doppler spread. An Extended Kalman filter is then applied as a near-optimal solution to the adaptive MD and channel parameter estimation problem. Examples are given to show the use and some advantages of this scheme.

This directory contains the Genetic Algorithm Optimization Toolbox for Matlab To use this, if you are local to NCSU and have AFS access to this directory, simply extend the matlab path using the following command. You can also place this command in a file called startup.m. Everytime you start Matlab in the directory containing this file, the path will always be Extended.

TFIND searches for one or more strings (boolean AND) in a text file. TFIND reports all lines where the string(s) were found (or NOT found by option). The search can be limited to a field in a fixed field (i.e. column oriented) list. An Extended search mode is available, where only letters and digits are relevant. Other options: case sensitive search, alternative errorlevel with number of hits, header line with file name, LFN, custom prefix

The Funambol J2ME Mail Client aims to be a light, easy to use, free email client for J2ME devices. The first release comes with a simple but effective UI, and a storage limited to the internal RMS only. This makes the application compatible with most of the phones around (minimum requirements are: MIDP2.0, CLDC 1.0, 512k of Storage). The mail synchronization using SyncML 1.2 over HTTP, thus removing any problem related to the access to IMAP or POP ports. The mail client synchonizes its address book with the one on the server, Its design is modular and can be Extended in future with other mail protocols, a more sophisticated UI and access to the phone s AddressBook or filesystem for the devices allowing this. See the javadoc for more information on the structure of the library.
